32 CRUCiFER*. [Barharea. 



E. Med. — About Ryde, occasionally. In a field at the back of St. John's fruit- 

 garden. Along the brook between Little Smallbrook and St. John's turnpike. 

 Banks of the marsh-ditches in Sandown Level, frequent. Sandown village. By 

 the stream-side between French mill and Baverstone or Bobberstone. Alverstone 

 bridge and by the stream at Weeks's, Dr. Bell-Salter. 



W. Med.— Plentiful by the roadside between Wilmingham and Afton farms, 

 Freshwater. In a ditch of ihe marsh-meadows of Guniet bay. In various places 

 about Brixton, near White-Court farm ; moist hedgebanks and drains near the 

 Grange, &c. 



Var. 8. Pods and their pedicels erect and in part appressed, somewhat oblique, 

 smaller than in the common state of the plant. An B. stricla Andrz. ? Very 

 sparingly by the roadside between Newbridge and Calbourne (a few plants only). 



Herb quite glabrous in every part. Root whitish, somewhat woody, tapering, 

 with several long stout fibres. Stems erect, pale green or sometimes purplish 

 below, from 18 inches to 2 feet or more in height, solid, stout, angular, deeply 

 furrowed, with sharp intermediate edges, simple or branched sometimes from the 

 base, the branches alternate, erecto-pateut, long and slender. Leaves somewhat 

 fleshy, very smooth and shining, alternate, strongly veined and waved or blistered : 

 radical and lower stem-leaves large, 6 or 8 inches long, lyralo-pinnatifid ; the 

 lobes ovate, roundish or oblong, distant and diminishing as they approach the base 

 of the leaf, with mostly several smaller intermediate lobules, entire, sinuate, waved 

 or slightly toothed, the terminal lobe very large, ovate, rounded or cordate at the 

 base, the petioles winged at their origin : upper stem-leaves shorter, less regularly 

 and deeply pinnatifid, the lobes fewer, narrower, the terminal one more deeply 

 sinuate, clasping by their almost sagittate bases ; the uppermost leaves obovate, 

 scarcely divided, deeply sinuato-dentate, clasping. Flowers numerous, bright yel- 

 low, in round-topped corymbose clusters, on 2-edged pedicels about as long as the 

 calyx, spreading or slightly decurved, when in fruit nearly erect, bracteate. Calyx 

 erect, the sepals nearly equal in height, tapering and somewhat pointed, greenish 

 yellow, caducous, with thickened concave tips, the two broader ones gibbous at 

 the base, the two narrower slightly keeled. Petals much longer than the calyx, 

 oblongo-obovate, entire, slightly emarginate or wavy at their extremity, tapering 

 into pale narrow claws, the limb spreading. Stamens upright, the longer pair 

 with an oblong, green, porrected gland, flattened below, gibbous on the upper 

 side between and exterior to them at their base, the shorter filaments each with a 

 much smaller, vertically compressed gland on either side of their ascending bases ; 

 anthers yellow. Style distinct, straight, a little thickened upwards, often inclining 

 to one side ; stigma sessile, capitate, glandular. Siliques in long clusters, very 

 numerous, crowded, glabrous, erect and partly appressed, on short pedicels that 

 diverge at an angle of about 22° from the stem ; about an inch in length including 

 the distinct, slender, straight and pei-manent style, which is nearly an eighth of the 

 whole, compresso-quadrangular and 2-edged, the valves strongly keeled and veiny. 

 Seeds numerous, exactly like those of the next species but much smaller. 



A handsome double-flowered variety is frequent in gardens, and it is sometimes 

 grown as an early spring salad, though much inferior to the next species for this 

 purpose, from its bitterness and comparative want of pungency. 



2. B. 'prmcox, E. Br. Early Winter-cress. American or Belle- 

 isle Cress. Vect. Land Cress. " Lower leaves Ij^rate, upper ones 

 pinnatifid, segments linear oblong entire, style much shorter than 

 the ovarium almost obsolete bent to one side, pods linear obtuse 

 compressed." — Br. Ft. p. 24. Erysimum, E. B. t. 1129. 



In cultivated fields, woods, waste places, and on hedgebanks, very frequent. 

 Fl. March— October. J . 



E. Med. — Fields about St. John's, very common. Between Seagrove and the 

 Priory. Woody ground between Quarr abbey and Ninham. Woods about 

 Cowes, at which place it has over-run the ground on the site of the new buildings. 

 About Sandown. Field near Fern hill, on the left of the footway from thence to
